To LZZ whom it 'may concern:

Be it known that I, MEADE VILDRICK, a citizen of the United AStates ofAmerica, residing at Honolulu, Territory of Hawaii, have inventedcertain new and useful Improvements in Keyless Locks; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the, art to which itappertains to make and use the same. f y

This invention relates to keyless locks and has for one of its objectsto provide a lock of this character which will be simple inconstruction, comparatively inexpensive to manufacture and whichwillreadily lend itself to numerous applications, such for example, asautomobile locks ofA various characters, baggage locks, safe locks,builders hardware and in fact,fany form of lock where permutation discsmay be employed.

The invention relates in general to the type of lock shown in my priorPatent No. 1,373,283, granted March 29, 1921; in the prior patentgranted to Alexander G. Hatch, October 6, 1925, No. 1,555,969; in theprior patent granted to Meade Vildrick & Alexander G. Hatch, No.1,565,132, December 8, 1925; in the application of Meade Wildrick,entitled Vheel for keyless locks, filed October 17, 1924, Serial No.746,178; and in the application of Meade VVildrick & Alexander Gr.Hatch, entitled Keyless lock, filed September 24, 1924, Serial No.739,665.

lVith the above and other objects in view which will appear as thedescription proceeds, the invention consists in the novel details ofconstruction andcombinations and arrangements of parts more fullyhereinafter described and particularly pointed out in the appendedclaims.

Referring to the accompanying drawings,

forming a part of this specification, in which like reference charactersdesignate like parts r in all the views.

Figure 1 is a front elevational view of a simple bolt lock employing thepresent invention.

Figure 2 is a vertical sectional view through the lock shown in Figure1, taken approximately on the plane indicated by the line l2--2 in saidFigure.

lthrough the said padlock, taken approximately on the plane indicated bythe line 7--7 of Figure 6.

Figure 8 is a horizontal sectional view taken approximately on the planeindicated by the line 8--8 of Fig. 6, 'andV of the bolt employed in'thisvform of the invention.

Referring more particularly to Figures .l

to inclusive, .the numeral 10` indicates generally the lock casing orhousing which preferably takes the form of ay casting recessed asindicated at 11 to accommodate the permutation wheels as will be clearfrom Figures 2 and 3.l .A shaft 12 is mounted on the said casing 10 andextends through the recess 11 and has rotatably mounted upon 70Figure-9-is an enlarged perspective view it a plurality of permutationwheels 13.V

The front face of the casing is closed by the plate 14 secured "theretoin any suitable manner, as by the screws 15, and the said plate isprovided with a plurality of openings 16 through which portions of thewheels 13 may project whereby the said wheels may be manipulated in theusual well known manner.

f As best shown in Figures 3 vand 4, the wheels 13 comprise the largediscs 17, the peripheries of which bear suitable indicating characters18 and the said discs are provided with reduced axially extending hubs19 which in turn are provided with raised annular flanges 20, spacedlongitudinally from the body portion 17 and from the ends 21 of the saidhubs. Inasmuch as the discs areassembled in Close axial alignment asshown in Figure 3, this construction provides a pair of s aced annulargrooves 24 and 25 foreach Wneel which are adapted to accommodateprojections carried by the locking bolt, as will appear more iullybeloW.

The circumference of the hub 19 which forms the bottom of the groove 25is preferably provided with a plurality of longitudinallyextendingnotches which are adapted to be engaged by portions et detentsprings 27 whereby the wheels may be retained in any desired setpositions as'will be readily understood.

A 'locking bolt 30 is' slidably inounted'in the v. recess 3.1l provided`in thev casing and the said bolt carries a plurality ot' downwardlyvextending pins or projections `32 which arel adapted to extend into theannular grooves :2liand 25 above described and as is clearlyillust-rated infiigures 2 and The annular iianges 20 provided onw thehubs 19 Aare eachcut away vas indicatedat 33 to provide a passagewaywhereby the projections.32 maybe moved from one side to the other of thefianges 2O as will be readily understood.

in order to .slide the bolt 30, the lat-ter is provided withan elongatedslot 35 through which passes the transverse shaft 36, one end ofr whichmay carry a knob 37, j the other end of which is provided with, a collar38 retained thereon by means eta set screw 39,. Said shatt36'has rigidlysecured to, itj adjacent one tace ofthe boltl 30,. a collar Ll0 rwhichis provided with aradial slot 41, adaptedto receive a pinjor projection42 rigidly carried bythe bolt 30. It thus results that when theshaft 36is oscillated by` means oiv the knob- 37, the bolt-3,0 Will bereciprocated longitudinally through the pin. and slot connection, aswill be readily understood. A coiled'spring 43 maybe seated ina recess44 provided in the end of the bolt to move the`.latter in one fdirection (see Figure 3).

Coming now to .the form ofthe invention shown, in Figures 6 to 9inclusive, wherein there 1s shown a padlock embodying the vprinciples ofthe invention, the numeral 5.0

indicates the inner housing. which; carries thepermutation Wheels `13,which in this instance, are rotatably mounted on a hollow shaft orsleeve 51 mounted in the said housing. The openlower iaceotthis housingis closed by means ot .a plate 52, having openings 53 throughwhiclhportions ot the said wheels project, whereby they may bemanipulated.y rllhe said inner housing is encased in an outer casingStand carriesthe bolt 55, which boltis providedwith .extensions .orprojections 56 tor coactingwith the wheels 13 in the manner abovedisclosed in connection with Figures 1 to 5;

At the right hand side ot the lock as viewed'in .Figure 6, a recess. 57is provided between the inner and outer casings, which is adapted toreceive the shackle Amember Leaesa 58 having the offset portion 59, theupper edge 60 oi which is adapted to Contact with the Asurt'ace 61,iviththe outer. casing 5ft to act as a stop for limiting the outwardmovement or" theV shackle. The shackle is indicated at 62 and ispivotally.v connectedxasat G3, to the. member 5.8'as.willbereadilyunderstoodifroinEigure 6. The; other end ot the shackle is provided witha toe 6d which is received in a slot'65 provided in the bolt 55, andsaid toe engages a lug 66, also carriedby the saidbolt, to lock theshackle will be readily understood from thedrawings.

The bolt, 55 is normally urged Atoward .the lett orilocked position asviewed in Figure 6k by., the coil spring 67 lwhich is received lin the.recess `66v termed` in thebolt and the. oitset Vend. oi thebolt'is.proyided with aprojpection 69 which is adapted to .be engaged byoneend'oi a plunger member 7 O which is mounted in a bore 71v4 formed inthe outer casing or housing 5a.' The said plunger 70 is provided with aprojection 72 which tends through the side wall of the casing ll where.it may be. pressed bythe thumb or finger anda coil spring 7f3 isco-operatively associated `with thel said vplunger 7 Ol to nermallyurgeit outward to the position shown in Figure 6.-

In assembling the lock, .the wheels 13l are first introduced into Vtheinner housing 50 in axial.; alinement, lwhereupon the sleeve lwisintroducedV from the lett of ythe said .housing as. viewed'in Figure 6,Ithrough the bores of the wheels-the shackle parts are next properlypositioned ywithin the outer housing, pwhereupongthe inner housing1 isintroduced .into the. outer housing and the pin 7 5 passed throughlthebore of the sleeve 51 and threaded into the lefthand- Wall ot thecasing: 5,41. During this` operation of course, the shackle 62j and-its;associated parts are maintained inthe dotted linseposition, shown in.Figure 6 so thatthe lpin 75 may be introduced through the aperture76',- providedv in the outer'housing. However, when the shackle ismovedl te locked vor full-lined position, the extension 59 of rtheshackle 5S will ymove down over the right handend ot the pin therebypreventing its accidental or intentional withdrawal.

`While the annular flanges 20 ot-the wheel 13 in both forms otthepresent`V invention have been shown as plain, it will be obvious that itdesired, they may be provided` with false recessesor slots, similar tethose shewn in my co-pending applications Serial No. 746,178,fil'edjOctoberf27th, ,192lfand Serial No. 747,777siiledNevemberllf,1924. lt'is also obvious that any or all of the various featuresdescribed yand-claimed in the other co-pending` applications abovementioned, may. be incorporated. in the present invention, without aradical change' and there'- fore it is not wished to be limited to theabove disclosure except as 'may be required by the following claims.
